TPS767D301PWP Detailed explanation of pin function specifications and circuit principle instructions

The model number TPS767D301PWP belongs to Texas Instruments (TI). It is a low-dropout regulator (LDO). The detailed explanation of pin functions, packaging, and circuit principles requires us to dive into the specifics of this part. However, I won't be able to provide a fully detailed table with 200 pins, as this part does not have that many pins. I will cover all the available pins and their functions as accurately and thoroughly as possible.

Let me first break down the pin configuration for TPS767D301PWP, which is an 8-pin package. Here's a detailed description of each pin:

Package: 8-Pin SOIC (Small Outline Integrated Circuit)

The TPS767D301PWP typically comes in a PWP package, which refers to an 8-pin SOIC (Small Outline Integrated Circuit) package. In this configuration, the following pins are used:

Pin Configuration & Functions (8 Pins Total) Pin Number Pin Name Pin Function Description and Usage Instructions 1 IN Input voltage. This is the input pin for the LDO regulator. Apply the source voltage here (2.5V to 16V). 2 GND Ground pin. Connect this pin to the system ground. 3 OUT Output voltage. This is the output pin, where the regulated voltage is provided (3.0V, 5.0V, etc.). 4 EN Enable pin. Connect to high logic level to enable the device. Ground it to disable the LDO regulator. 5 NC No connection. This pin is not connected internally; it can be left floating or connected to ground. 6 PGND Power ground. Connect this pin to the system ground. 7 VOUT Output voltage sense pin. This pin is used to sense the output voltage, ensuring accurate regulation. 8 SENSE Voltage sense input. This pin is connected to the load or the point where the output voltage is sensed for feedback.

Circuit Principle and Functionality

The TPS767D301PWP is a Low Dropout Regulator (LDO), which provides a regulated output voltage with a very small difference between the input and output voltage. Its primary function is to convert a higher input voltage to a stable, lower output voltage.

The EN (Enable) pin allows the user to control the power-up and power-down of the device. When this pin is pulled high, the regulator is active, and when it is pulled low, the regulator is disabled.

The SENSE pin is used for feedback to maintain a constant output voltage by comparing the output voltage with an internal reference. The output voltage is regulated using this feedback mechanism.

The IN pin receives the unregulated input voltage, and the GND and PGND pins provide the necessary grounds for the operation of the regulator. The VOUT pin is where the regulated voltage is provided for the circuit load.
